Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 35 ( subtract 25 from both sides )
x² - 10x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 10 + 25
(x - 5)² = 35 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
x = 5 ±
That is the second option on list
4 ( x + 5 ) = x + 8
4 * x + 4 * 5 = x + 8
4 x + 20 = x + 8
4 x - x = 8 - 20
3 x = -12
x = -12 / 3
x = - 4
hope this helps!
Answer:
the answer is wrong!! is 8,560 total cost
Step-by-step explanation:
170x48(4 years) = 8,160
8,160+400(down) = 8,560 total cost
This is how the sketch should look on your graph!
Is that the whole question? It does not specify, so that means there is a 50/50 chance for either.
